This paper discusses a technique to simplify dynamic tests of power supplies. The technique is based on the injection of an external signal into the feedback loop of a dc-dc regulator, which makes it operating as a dynamic load, if connected to the output of the power supply under test, or as a dynamic source, if connected to its input. The technique allows to easily observe load/line transient response and AC response of a power supply by means of basic laboratory instrumentation. The theory is discussed in this paper, whereas examples of application are presented in the companion paper Part II.
